Premium Line Equipment

CMWTEC’s premium battery finishing line equipment represents the highest standard in fully automated battery production technology. Designed for original equipment (OE) manufacturers of lead-acid, AGM and EFB batteries worldwide, our Premium Line delivers precision, reliability and maximum throughput across every stage of the battery finishing process.

From AGM vacuum acid filling and volumetric initial filling to battery formation charging, high-rate discharge (HRD) testing, high-voltage testing and end-of-line testing – our Premium Line machines cover the complete battery finishing workflow. Each machine is engineered for seamless integration into fully automated battery assembly lines, minimising downtime and maximising output quality.

The Premium Line includes advanced battery assembly solutions such as plug insertion, post-brushing, post-greasing and battery labelling, as well as intelligent battery handling and conveyor systems. All machines can be combined into flexible, modular production lines tailored to your exact process requirements.

Built on decades of engineering expertise at our headquarters in Runkel, Germany, every Premium Line machine meets the highest standards of quality, precision and safety – exactly what OE battery manufacturers demand.
